LAM P-HANGER.

SPECIFICATION forming part of Letters Patent No. 444,920, dated January20, 1891.

Application filed May 7, 1890,

To all whom, it may concern.-

Be it known that I, MORTIMER McRoBERrs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Lamp-Hangers, which arefully set forth in the following specification, reference being had tothe accompanying drawings, in Which- Figure 1 represents a sideelevation of the upper portion of a lamp-hanger harp embodying myinvention; Fig. 2, a similar view of the lower portion of the same, themiddle portion of the harp being broken away; Fig. 3, an elevation ofthe inner face of the cap-piece or fastening for use with Fig. 1 Fig. 4,a similar view of the corresponding piece to be used with Fig. 2; andFig. 5, an elevation similar to Fig. 1, showing a modification in thefastening device.

My invention relates to devices for suspending lamps from the ceiling ofa room or any other support, and more particularly to that class oflamp-hangers in which the frame of the hanger is shaped somewhat like aharp and-is generally known to the trade as the harp of the hanger.

My invention consists in making this l1arpframe in twoindependent andseparate pieces, which areconnected together at top and bot tom bydevices which permit the ready adjustment of the said parts whenever itmay be desired.

I will proceed to describe one way in which I have carried out myinvention in practical form, and will then point out definitely inclaims the particular improvements which I believe to be new and wish toprotect by Letters Patent.

In the drawings, A represents the harp of a lamp-hanger, the centralportion thereof being broken away. Usually this device is composed ofone piece of metallic wire or a metal rod of a suitable size bent'intothe re quired shape and having its two ends connected together by asuitable device either at the top or bottom of the harp, generally thelatter, Where these two ends are connected by securing them to the partor piece on or in which the lamp is directly placed. In my improvement,however, this harp is formed from two distinct and separate parts a,which Serial No. 350,831. (No model.)

7 are formed from the material usually used for this structure, and arebent so as to each constitute one-half or one side of the harp. As shownin Figs. 1 and 3 of the drawings, the upper ends of these two rods arebent inward and downward, so as to form either bends or hooks to aboutparallel with the length of the harp, and at their lower ends the rodsare bent outward and downward to form similar hooks a This is to providefor connecting the two pieces of the harp at each end by a suitable clipor clamping device in such manner that they cannot be turned in theirsockets.

The clamping device for connecting the upper ends of the side rodsconsists of a main part or body B, one face of which is virtually flat,and in this face is sunk arecess h of substantially rectangular form andhaving at its upper edge circular grooves 11', extending outward on eachside to the edge of the body. It is also provided with a ring 12 at the'upper end, which is to serve as the suspensionring of the hanger, andon its under side with a depending hook 79 upon which the smokebell maybe hung. A cap-piece Ois provided of size and shape to conformsubstantially with the body or central portion. of the piece B. This capon its inner face, which is practically fiat, is also provided. with asunken re cess c, conforming in size and shape substantially to therecess in-the body 13 and having similar side grooves c. The depth ofthese recesses is intended to be about one-half the diameter of the rodsa, and are adapted to receive the bent ends a of these rods, which areconnected together by placing the hooked ends a within the recess in thebody B, as seen in Fig. 1 of the drawings, and then placing upon thisbody the cap 0, the recess of which receives the projecting parts of thehooks, and will therefore hold them firmly in place when the cap issecured to the'body B, which is done by short screws. At the bottom ofthe harp the ends of the side rods to are connected together in asimilar way. The main body D of the clamping device is here shown as thedirect support for the lamp, and is provided with a short projection dat its upper end to fit the socket in the bottom of the lamp, this beinga well-known device for this purpose. The central portion or body ofthis piece D is cut away to about half its thickness, and in the hatinner face thus formed there is provided a recess d, which may besubstantially the same as just described for the upper clamp, but ispreferably formed as shown in Fig. 2 of the drawings, in which thecentral portion of the recess is divided by ashort rib d extendingupward part way across'the recess. There are the circular grooves cl"extending out to each side of the piece the same as in the upper clamp,and so there are provided two bent grooves or-channels which are adaptedto receive the respective hooks or bent ends a at thelower end of theharp, as seen in Fig. 2 of the drawings. These ends are secured inplace, substantially the same as at the upper end, by means of a cap E,which is recessed to correspond with the main part of the clamp D, thebent grooves e e, sunk in the inner face ofthis cap, corresponding tothe grooves just described in the main body. This cap is applied to theflat face at the middle of the piece D, and fastened thereto by screws,as already described for the clamp 13. It will be seenthat when the twoside rods a are' thus connected together a complete hanger is formed ofthe harp variety, and that it is firm and substantial, for the rodscannot turn in either of the clamps by reason of the hooks on theirends, so that the lamp-supporting piece I) will be held in its properposition to retain the lamp in a vertical position, and the suspendingpiece B will also be retained in a similar vertical plane. At the sametime the parts can bedisconnected with great readiness. The entirehanger may be taken to pieces in a few moments and as readily puttogether again for service. therefore greatly facilitates shipment, forthe separate-parts of the hanger can be packed together in a very smallspace and a large number shipped within a space which would accommodatecomparatively few of the old hangers made in one piece. It also securesgreater economy in expense of the article itself, for if one of the siderods is broken or in any way injured, so as to be unfit for use,it.-is'only necessary to detach this injured side rod a and replace itwith a new one, whereas in the old style of construction the entire harpwould be thrown away.

I have described above one particular style of clamping devices forconnecting the respective ends of the side rods a together. Theseconnecting devices may, however, be greatly varied. In Fig. 5 of thedrawings I have shown one modification for the upper connection. In thiscase the connecting-piece F has a central perforation f bored throughThis construction it horizontally, corresponding to the size of the siderods a. i The outer ends of this perforation are threaded right andleft, respectively. The upper extremities of the rods to are similarlybent in the usual way to bring them into a horizontal position andthreaded right and left to correspond with the threaded openings of theconnecting-piece. It is evident, then, that if the threaded ends of therods are just inserted in the opposite ends of the perforations f andthe connecting-piece F be turned in the proper direction the said endswill be drawn inward and so connected together by the' piece F, as seenin Fig. 5 of the drawings. WVith this device, however, there is nothingto prevent the turning of the suspension-piece F upon the rods, which isnot of very great importance at this end of the harp; but suchaconnection will notanswer for the lower end of the harp, because thesupporting-piece of the lamp must be held from turning.

In some instances a ring is provided at the bottom of the harp for thereception of the lamp, and when my improvement is applied to thisconstruction of the. device the lower ends of the two side rods a aresimply connected to the ring in any convenient way. I mention thesechanges simply for the purpose of illustration and not for the purposeof indicating the only modifications that can be made, for it is obviousthat any person skilled in the manufacture of these hangers will be ableto devise many different devices for connecting the two sections of theharp together.

The characteristic feature of my invention is the divisionof theharp-frame into twodistinct and separable parts, which may be connectedtogether at top and bottom by any suitable device, whereby theadvantages are derived which have been set forth above.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a lamp-hanger, the independent and separate side rods a, providedwith hooks or bends a at their upper ends and a at their lower ends, incombination with the suspendingand clamping device B O, recessed andadapted to receive the books a, and the lamp-support and clamping deviceD E, recessed and adapted to receive and clamp the bent lower ends ofthe side arms, substantially as and for the purposes specified.
